I could understand where you are coming from. unfortunately, your incident and this are not the same. in your case, its an accident that you tried hard to salvage and others are not affected. In this case, the boy has stubbornly refused the request from the teacher to leave his seat and clean himself up. The classmates are badly affected by a pool of poo that stink the entire classroom and urged him to go to the office to change himself, which he ignored.
If he were really to see this in the future, we hope he will be a better parent. To educate his kids that physical hurting that result in his classmate suffers from months of bleeding is not a right thing to do. And it is even more wrong for his parents to get another adult to threaten his victim. Imagine how fearful and helpless (and physically injured) victim barely 8 years old was when he is cornered by adult sent by the boy’s parent, how other kids unknowing the actual situation perception of the victim. These are all reported to the school but no action is taken. Nevertheless, this is not the intention of the post here.
